REGISTER.

Application filed March 25, 1922. Serial No. 546,568.

This invention relates to air flow control devices.

This invention has utility when incorporated in a foul air escape register.

Referring to the drawings:

Fig. 1 is a section of an embodiment of the invention in a building installation; I

Fig. 2 is a section on the line IL-ll, Fig. 1, on an enlarged scale,'showing the foul air escape register;

1 Fig. 3 is a perspective viewof one of the vanes or louvers of the register;

Fig. 4 is a front view, with parts of the screen broken away, of the register of Fig. 1

Fig. 5 is a section on the line V-V, Fig. .4; and

Fig. 6 is adetail View in enlarged section of one of the lo-uvers as mounted.

Motor 1 is shown as connected to drive fan 2 in impelling or drawing in air to pass under furnaces 3 to cold air chamber 4:. The air rising through the heated regions up between the furnaces 3 may ascend into hot air or plenum chamber 5. A hinge bearing 6 for vane 7 permits a mixing of the cold air from chamber 4 with the hot air from chamber 5 thereby allowing a regulation of the temperature in duct 8 from these chambers 4:, 5. This duct 8 communicates with riser 9 having hot air supply register 10 to room 11. This room 11, near the lower portion or floor, has outlet or screen 12 in communication with foul air duct riser 13 which may extend to a vent in the roof or out-side of the building containing the room 11.

This screen 12 is shown as comprising a piece of sheet metal which has been slotted and then stretched open to form a mesh or screen. This screen 12 is shown as anchored against a main frame 1 1 having a lip or flange 15 folding over the edge of the screen 12 thereby forming a frame for this screen 12. From this folded frame portion 14:, 15, there extends rearwardly a flange 16. This flange 16 terminates inbent portion 17 serving to anchor lateral housing portion 18. This frame 14, 15, 16, has horizontally dis posed openings or bearings 19 in the side flanges 16 and in medial flange 20. These bearings 19 are disposed in parallel rows and in a plane parallel with the screen 12, said plane being vertical. These bearings 19 carry bars 21 upon which, between the flange 16 and the flange 20, are mounted the vanes leuver preper.

Each louver is herein shown as embodying an upper curved portion 22 for mounting the vane upon the bar 21. Hanging downwardly from this mounting portion 22, the vanes or louver-s are herein shown as having major concave portions 23 curved to concave toward the screen 12. Below these major portions 23 each louver or vane is shown as having a minor concave portion 24 for nesting over the fold 22 about the bar 19, below the bar mounting said louver. This nesting by the concave portion 24 is packed by felt packing 25.

The general configuration of each vane or louver is such that when freely hung it is approximately balanced. That is, its center of gravity as extended from the central portion of the axis, or the axis of the bar 21, is such that in holding the packing 25 in position against the fold therebelow it just swings into such position that there is a minimum of resistance to flow of air from the room 11 past this louver. As shown in Fig. 6, the central vertical line 26 may be the balancing plane and the louver is shown as hanging to approximately swing freely in the vertical position independently of the nesting of the packing 25 therebelow, with the said next lower vane or louver.

In practice this means that the flow of air from the room 11 is such that it may readily occur with a minimum resistance. However, any reversal. of air current, say by downflow into the shaft 13, may not be discharged into the room 11 for lowering the temperature of the room 11, because the vane at once swings to resist action of any such flow contrary to the foul air release flow. The lower vane or louver is shown as having the packing somewhat diflerent from the top and intermediate louver members. This lower terminal of the lower vane is formed with a groove 27 for receiving a packing strip 28, of felt, which in the suspension of this lower louver member may swing into sealing position in the general register closure.

What is claimed and it is desired to secure by Letters Patent is:

1. In a ventilation installation a room having an air inlet and an air outlet, a register for the outlet including concave vanes and mounting pivots for the vanes from which the total effective wine extent of the at register closing position, such balanced position being due solely to the normal gravity hang of the respective vanes from their mounting pivots and such vanes having their entire closure effecting portions move upward for opening the register.

2. A register comprising parallel horizon tal bearings, bars in said bearings and vanes mounted on said bars and including a vane pivoted as to its total effective vane extent to depend from an upper bar, said vane being doubly concave in adjacent portions on one side thereof and hung to be balanced at closed position by the normal gravity hang of the vane, said vane having its entire effective closing portion move upward in opening.

3. A register comprising parallel horizontal bearings, bars in said bearings. vanes having portions embracingsaid bars and having the total effective vanes extent depend therefrom as register closing means, said vanes having major and minor concave adjacent portions on the same side thereol and said vanes being at gravity balance in closed position to have the minor concave portions coact with the adjacent bar enibracing vane portion therebelow as: a seal, and said vanes in opening said seal having the entire vane depending portion mo e upward.

In Witness whereof We allix our signatures.
